👁️‍🗨️ Watch the animation to learn more about glycolysis

Answer these questions while watching

1. Where is the location of glycolysis? 

2. What are the two main phases of glycolysis? 

3. What is the purpose of the first phase in glycolysis?

4. What are the products of the second phase of glycolysis? 

Diagram on the left shows a good summary of glycolysis process (important molecules involved were mentioned). 

Using the diagram and animation above, fill in the blanks below: 

At the end of glycolysis, the products formed per glucose molecule are as follows:

• ____  pyruvate molecules

• ____ NADH molecules 

• ____ ATP molecules 

Take note that: 

NADH = reduced NAD 

👁️‍🗨️ Watch the animation 0:00-2:04 to learn more about substrate- level phosphorylation. 

1. What is substrate- level phosphorylation? 

2. When does substrate-level phosphorylation occur in respiration? 

👁️‍🗨️ Watch the animation 2:18- 3:07 to learn about the differences between substrate level phosphorylation and oxidative phosphorylation.
